LWGY Series Liquid Turbine Flowmeter

Features & Options

• • Cost-Effective: one of the most affordable flow metering solutions on the market. Ideal for multi-point monitoring and budget-conscious projects, significantly reducing total installation costs.
• • No External Power Required / Local Direct Reading: Purely mechanical operation, requires no external power supply. Real-time visual flow indication via transparent tapered tube—perfect for hazardous areas, remote locations, and off-grid installations
• • Simple Structure, Easy Installation & Maintenance: Extremely simple and robust design. Vertical inline installation with minimal maintenance required, reducing downtime and labor costs
• • Low Pressure Loss, Energy Saving: Minimal pressure drop (only a few inches of water column). Allows use of lower-power pumps, resulting in significant long-term energy savings
• • Excellent Repeatability for Reliable Monitoring: While not the highest absolute accuracy (typically ±2%~±4% of full scale), it offers excellent repeatability, making it ideal for stable process monitoring where flow trend is more critical than absolute value
• • Wide Material Options for Various Corrosive Fluids: Available in glass tube, metal tube, and engineered plastics. Float materials include 316L SS, PTFE (Teflon), and Hastelloy C, suitable for water treatment, chemicals, acids, alkalis, and other corrosive fluids
• • Optional 4-20mA / Pulse Output for Automation: Optional transmitter with 4-20mA or pulse output for seamless integration into PLC / DCS systems, enabling remote monitoring and industrial automation
• • Optional Alarm Switches for Flow Limit Control: Optional high / low limit alarm switches trigger alerts when flow exceeds set points, protecting downstream equipment from damage
• • Ideal for Low Flow & Small Line Sizes: Excellent performance on small line sizes (DN15 ~ DN50) and low flow rates. Widely used in laboratories, chemical dosing systems, and gas analyzer calibration
• • Intrinsically Safe / Suitable for Explosive Atmospheres: Purely mechanical with zero electrical spark risk—intrinsically safe. Directly applicable in explosive atmospheres such as chemical plants, oil refineries, and natural gas facilities without additional explosion-proof protection.
